Add Prolog in a Qt application
-
Hello everyone,
I need to add an AI in my application and to do that, I decided to work with Prolog.
I downloaded SWI-Prolog here (32bit version, as I build my project with Qt 5.8 MinGW 32bit), and I installed it.Then I added the libswipl.lib to my project (right clic / Add library on QtCreator), here is what my .pro looks like :
#------------------------------------------------- # # Project created by QtCreator 2017-03-19T17:55:04 # #------------------------------------------------- QT += core gui greaterThan(QT_MAJOR_VERSION, 4): QT += widgets TARGET = TestProlog TEMPLATE = app SOURCES += main.cpp win32: LIBS += -L$$PWD/'../../../../../Program Files (x86)/swipl/lib/' -llibswipl INCLUDEPATH += $$PWD/'../../../../../Program Files (x86)/swipl/include' DEPENDPATH += $$PWD/'../../../../../Program Files (x86)/swipl/include' win32:!win32-g++: PRE_TARGETDEPS += $$PWD/'../../../../../Program Files (x86)/swipl/lib/libswipl.lib'After that, I wanted to test if everything is ok, so I took an example on the internet, here is my main.cpp :
#include <QApplication> #include <QInputDialog> #include <QMessageBox> #include <SWI-Prolog.h> #include <SWI-cpp.h> #include <SWI-Stream.h> int main(int argc, char *argv[]) { QApplication a(argc, argv); PlEngine e(argc, argv); QString pal = QInputDialog::getText(0, "Palindrome check", "enter text"); PlTerm ATOM = PlAtom(qPrintable(pal.toUtf8())), LIST; PlCall("atom_codes", PlTermv(ATOM, LIST)); if (PlCall("reverse", PlTermv(LIST, LIST))) QMessageBox::information(0, "outcome", "is a palindrome"); else QMessageBox::information(0, "outcome", "is NOT a palindrome"); return 0; }It successfully build, but when I run the application, it crashes immediately. I tried to debug it by setting a break point on the first line and and error ocurred "During startup program exited with code 0xc0000135".
If I comment Prolog related lines, the application runs normally.What am I doing wrong ? Did I missed something ?
Thanks in advance for your help, have a good day !
